られている。(Prior Art) A crystallization initiator for a supercooled salt solution breaks the supercooled state of a supercooled salt solution to start salt crystallization. Such a crystallization initiator is used as a device for initiating crystallization in a heat storage agent that utilizes the heat generated when sodium acetate trihydrate is crystallized from a supercooled aqueous sodium acetate solution.

るものである。Conventionally, the following devices have been proposed as crystallization initiation devices for supercooled salt solutions. One of them is a non-ferrous metal disc with small holes that changes its flat surface state when pressed, like the cap of an oil can. The purpose is to stimulate the supercooled salt solution by passing through the small holes and break the supercooled state. Another method is to place a pair of electrodes in a supercooled salt solution and apply a voltage to the electrode surface or in the supercooled salt solution (to form crystal nuclei that become heavy crystals, thereby breaking the supercooled state. This is what we are trying to do.
しかしながら前者は小孔の大きさによっては晶出を生じ
ないことがあり、しかも小孔の大きさを理論的に求める
ことができないため実用性が高いとは言い難い欠点があ
る。However, the former method has the drawback that crystallization may not occur depending on the size of the pores, and furthermore, the size of the pores cannot be determined theoretically, making it difficult to say that it is highly practical.
また後者は電源が必要となることから装置が大掛かりに
なり、蓄熱剤に用いるには好ましいものではない。In addition, the latter requires a power source, making the device large-scale, and is not preferable for use as a heat storage agent.

a presser slope made of metal and larger than the opening of the container;
It is characterized by a crystallization initiation device for a supercooled salt solution, which houses a spring made of a metal different from the inner layer metal of the container, and presses a presser plate against the inner surface of the periphery of the opening of the container so that the pressing plate can be moved up and down by the elasticity of the spring. shall be.

できる。その晶出開始は次の理由によると推測される。(Function) This crystallization initiator is placed in a supercooled salt solution and can start crystallization of salt by repeatedly pressing and releasing the presser plate to move the presser slope up and down within the container. . The onset of crystallization is presumed to be due to the following reason.

出が始まると推測される。In other words, the spring is repeatedly deformed by the vertical movement of the presser plate, and as a result of the repeated deformation, the electrons and atomic nuclei within the spring separate and collect, and when the amount of collection reaches a certain amount, the spring is made of a different metal. It is speculated that a current flows from the spring into the inner layer of the container, which stimulates the formation of crystal nuclei that become salt seed crystals in the supercooled salt solution, thereby breaking the supercooled state and starting salt crystallization. be done.

をスムーズにするためのものである。The outer layer 18 made of plastic is intended to prevent the potential of the container inner layer 20 from being affected by friction or the like in the supercooled salt solution. In addition to stainless steel, metals forming the inner layer 20 include copper silicide, lead, lead-antimony alloy, lead-tin alloy, iron, iron-silicon alloy, molten magnetite, platinum, silver, aluminum, copper, zinc, antimony, and tin. , mercury, various amalgams, chromium, cadmium,
Examples include beryllium copper and phosphor bronze. In addition, a narrow window 23 is formed in the container 12, and when the holding plate 14 moves up and down in the supercooled salt solution, the solution in the container 12 is discharged through the narrow window 23 and held down. This is for smooth vertical movement of the plate 14.

Moreover, the inner diameter of the container 12 is smaller than that of the container 12.

The metal forming the container is different from the metal of the container inner layer 20 and is selected from those listed above. The pressure plate 14 is pressed against the inner surface of the periphery of the container opening 22 by the elasticity of the spring 1G. Note that the spring 16 is not limited to a coil shape, but may be a plate shape.
